Automa-Tonne

Automa-Tonne is a puzzle-platformer about a robot who must use its ability to switch its mass between light and heavy modes in order to solve puzzles and reach the exit of a mysterious laboratory.

(Yes, I know an automaton is not the same thing as a robot, but I had to make a pun somehow!)

This is my first full game, so feedback would be much appreciated!
